Castle Rock Reservoir, Colorado: Fishing Spots and Seasons

• Overview

  Castle Rock Reservoir lies in Huerfano County, in Colorado. Farm and woodlot runs right down to the water. It measures about 43 acres, which is a comfortable size for bank fishing. Head to Walsenburg, 2.4 miles away, for anything you forgot. The nearest city of size is Pueblo, 47 miles away. There is no boundary nearby to worry about.

• Where to Fish on Castle Rock Reservoir

  Without a survey to go on, judge depth from how the bank falls away. A reservoir gives you a hard edge, a shelf, and not much else. Inflow corners move water, and moving water gathers fish. County-wide records name cutthroat trout, black-spotted cutthroat trout, brook trout, rainbow trout and white sucker. Records at this level tell you what is in the area. At Castle Rock Reservoir light and wind decide more than tackle does.

• Seasonal Patterns

  Expect July to average close to 72°F, with January the cold end at about 32°F. Some winters cap it and some do not. In milder years the edges alone go, and the middle never sets. April and May are the settled weeks, with October close behind. That is the shape of the year on Castle Rock Reservoir.

• Tackle & Baits

  No public source sets out the position on this bank. Public mapping marks it as seasonal water rather than permanent. Public data shows nothing built here, so treat the whole approach as informal. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Local rules can differ across the county line, so check where you stand. Some ground is open by custom rather than by right, so tread carefully. Failing this one, try Farr Lake, 2.5 miles away. Check the position on Castle Rock Reservoir before loading the car.
